Celtics would take a chance on DMC and they have plenty of picks to offer back for him. Also you dont trade that much talent to a team in your own state. If he works out and gets Clippers anywhere further in the playoffs you wont live that down with your fans. Trade him East. Celts, Bucks, Atlanta, 76ers, Wizards, Magic are all teams that could put together a decent package for him and might be willing to make a move for him. Those all might not be a good fit but Kings dont need to worry about that.
I don't know if worrying about another team in your own state helps.. you get the best deal possible for your team.
Memphis traded Pau Gasol for Marc, and they've been successful since... one could even argue MEM won that trade even though the Lakers got a couple of rings out of Pau.
You make the best deal for your own franchise.. worry about the other teams later.
